There is strong experimental evidence for physics beyond the Standard Model (SM). Some of the most compelling hints are for example the observation of neutrino oscillations [1]}, requiring massive neutrinos, or the latest Planck measurement of the CMB power spectrum, hinting at an overall dark matter (DM) abundance of \(\Omega h^2 \sim 0.26\)  [2]}.
Pinning down the correct particle physics model responsible for giving mass to the neutrinos and explaining the effect of dark matter with the correct relic abundance has been the goal of many particle physicists over the past decades.
Many dedicated experiments have since been built to test interactions of both neutrinos and dark matter in order to gain a better understanding of their enigmatic nature. In this note, however, we want to focus on what complementary information we might gain from studying their interactions at LHC multipurpose experiments like ATLAS or CMS. To this purpose we will investigate the sensitivity of these experiments to ultralight dark matter candidates via appearing displaced jet signature in sec:uldm. In sec:nus we will then argue that a similar search strategy can also be exploited to observe interactions of the copiously produced neutrinos at the LHC.
